'1 "00 whom it may concern Be it-known that l, Josnrn Hairs, a citizenof-the Republic of France and residing at Paris. Seine Department, No.19 Rue Constance, in the Republic of France, en-' bolts whereofone isactuated by the sliding movement oit'tho inner handle and the other bythe rotation of the said handle, The

said ii'nprovements have for their object to afford a very simpleconstruction for a fastening device of this character and to render thesaid device very easily mounted upon doors, these latter being out, into only a slight degree and in a ,very simple shape. For this purpose.the inner handle draws with it in the vertical movements thereof a psponding lug 6 which is secured to the sald sliding member which drivesback one of the bolts through the intermediary or a bellcrank lever ormore directly by means of To mount the'said casing upon the door, it

will-suffice to form a corresponding rectangular out out portion thereinwhich has but a slight depth, thus requiring a minimum amount of laborand without weakening the said door.

The following description, together with the accompanying drawings, setsforth three embodiments of my invention.

Fig. 1 is a side elevation of the first embodiment.

the main plate. is vertically guided at thebottom by a cut out portionof theframe 8 and at the top- Fig. 2 is a front eievation of the same,viewed from the interior.

Fig. 2:3 is a side elevational view showing the bolts drawn in. thepartitions oi the lock being removed.

Fig. 1 is a longitluilinal.section on the line A A Fig 2.

Fig. 5 is a diagrammatic view of the mechanism of the second embodnnent,the closing springs and the operatingdevice by the outer handle beingremoved.

Fig. 6 shows a third embodiment, with the bolts in the closing position,and N i Fig. 7 a like view with the first bolt opened.

Fig. b is a section on the line A Fig. 6. Fig. 9jis an elevational viewof the inner handle of the preceding lock, and

Fig. 10 is a cross-section of .the'said,

handle.

1 and 2 indicate two bolts of the said lock which are guided withinsuitable cut out portions of a frame 3 secured to the main plate oftherlock, 4t, the said frame constituting partitions upon the four sidesof the latter. One end of the said main plate is bent'up to form across-member 5, and the frame 3 is provided with a correcross-member. On,the opposite side, the said frame has a cut out portion 7 for lightening the same. Across the said bolts is dis posed a sliding member 8having pivoted thereto, the inner door handle 9 whose shank 10 extendsthrough a vertical-groove 11 in The said sliding n'iember by the groove1].. It is provided at the lower part with project-ion 12 adapted toengage. one arm of a bell-crank lever 13 pivoted at 1 1 upon the mainplate, the other arm ofthe said lever entering in contact with ashoulder 15 of the bolt 1 in such manner as to impel thesaid boltinwardly against the action of the spring 16.

' To the shank 10 oi the inner'door handle is secured a finger L7engaging the shoulder 18 of the bolt 2 whereby the latter shall beimpelled against the action of the spring 19. When the sliding member islowered, Fig. 2, the finger 17 is now engaged between the stop pieces20, 21 secured to the main plate and is thereby prevented from swingingto the right or left. In the main plate and in a lug of the sa id frameis journalled the hub 22 of a striker 23 adapted to impel the bolt 2inwardly by acting upon the shoulder thereo'l 2st. The hub 22 isprovided with a square aperture adapted to receive the shank of theouter door handle, not shown. When the bolt 2 is thus driven back, itdrawn along the bolt 1 by means'ot a finger 25 secured to the first boltand engaging a finger 26 secured to the second bolt. When the door isclosed, the said sliding member is lowered and the doorhandle J isthereby prevented from turning, the finger 17 being held firmly betweenthe members 20, 21. The lock may now be'opened from the eX- terior inthe usual manner, the bolt 2 being drawn inwardly by the striker 23 andthe bolt 1 being also drawn inwardly by the bolt 2 and the fingers 25,26.

To open the lock from the interior, it is required to raise the handle 9in first place and to then turn the same. The first movement has theeffect of lifting the sliding member 8 in such manner that theprojection thereof 12 shall cause the lever 13 to swing, this latterimpelling the bolt 1inwardly. The second movement effects the rotationof the finger 17 which is now disengaged from the members 20, 21 andimpels the bolt 2 inwardly. Upon releasing the door handle 9, thesprings 16, 19 cause the bolts to return outwardly, whereupon the lever13 is returned to the inoperative position and obliges the slidingmember to descend, whereas the finger 17 is caused to as sume theupright position and is brought back between the stop pieces 20, 21.

The form 0'1 construction which is shown diagrammatically in Fig. 5difiers from the preceding form by the fact that the lever 13 issuppressed, the projection 12 of the sliding member 8 and the shoulder15 of the bolt 1 having the shape of inclined planes which are so formedthat the lifting of the said sliding member shall efiect the backwardmovement of the said bolt and that the return movement of this latterbolt shall effect the lowering of the said sliding member. One of theinclined planes 12 01 .15 may be replaced by a rounded surface or aroller. L

In the. form of construction shown in Figs. 6, 7 and 8, the slidingmember 8 is ended at the level of the shank 10 of the door handle,thereby afi'ording a larger space for thefinger 17 controlling thesecond bolt, and enabling the latter member to be given all the requiredstrength. The lower part of the sliding member 8 is provided as in thepreceding case with a projecting portion 12 engaging the bell-cranklever 13 in such manner as to effect the opening of the bolt 1, Fig. 7,upon raising the handle 9. The said handle is horizontally disposed, asshown in Fig. 8, and it may thereii'ore- 'ie very easily raised, andmoreover, the passenger will instinctively execute this movement. Tosimplify the construction it comprises a plate 27 support ing the shank10 provided with a recess 28 wherein the handle properly as called ismaintained by a separate bracket 29 which is secured for instance by ascrew 29. To facilitate the lifting movement of the said handle, theplate 27 is provided with a row of balls 30 adapted to roll upon thesurface of the main plate l.

31 is a projection adapted to guide the finger 17 and 32 a projectionadapted to guide the sliding member 8.

Claims 1. In a fastening device having two bolts, the combination of avertical sliding member carrying the inner handle and a finger securedto the shank of the said handle, the

said sliding member being adapted to effect a longitudinal movementwhereby one of the said bolts shall be drawn into the opening position,the said finger being adapted to act upon the other bolt in such manneras to impel the same inwardly upon rotating the said handle.

2. In a fastening device having two bolts, the combination of a verticalsliding member carrying the inner handle, a finger secured to the shankof the said handle, a striker provided for the outer handle, and a frameconstituting at the same time the walls oi the said fastening-device,the guides for the said bolts and for the said sliding member, and oneof the bearings of the striker of the outer handle.

3. In a fastening device having two bolts and comprising verticalsliding member carrying the inner handle and a finger secured to theshank of the said handle, a plate constituting the base of the saidhandle and provided with balls whereby it is enabled to slide upon'themain plate, whereupon the handle properly so called is maintained by aremovable member.

In testimony, that I claim the foregoing as my invention I have signedmy name in presence of a subscribing witness.
